Caulking fiberglass shower surround

Do you suggest caulking along the bottom of the 3-piece surround (where it meets the tub)? I always have, but a friend claims there is a lip created there to prevent water from getting where it shouldn't go. We seem to agree on the need to caulk the vertical seams in the surround, but not the horizontal one along the top of the tub. I have had no problems with the caulk staying just discolors with time and needs replaced. Thanks for your suggestions!

I would not do it, reason being is if water some how did end up behind the panels the caulking would act as a dam and hold it in.
There's a lip around a tub on three sides, so water would have to run up hill to be able to get in.

Personally I do caulk these when I install them. BUT--I run a small bead of caulk near the edge so that when I press the panel in place it will sort of "sqish" out. I let this set a few minutes then trim off only what can be seen. Along the bottom edge I skip about a half-inch (1/2") every foot for "breathing".
